This is in Lee County VA, just off Hwy 766 (36.83452, -82.97876). It’s on private property and is derelict. There was an earlier Robbins Chapel School. There’s a picture of it on this webpage. This structure looks to be from the 50s.
The real Robbins Chapel is near here, on Hwy 606. Nearest town is Keokee.
This is a remnant of one of the 200 coke ovens that once lined the valley behind the extant power building along what is known now as Fire Hall Road in Keokee VA. A rail spur brought the coal in and took the coke out, bound for steel mills in the north.
If you look carefully, you can see the curve of the right side of the heavy piece of brickwork. That’s firebrick that lined the inside of the oven.
My friend Mr. Stone (an expert in topo maps, Google Earth and the old coal mines and towns in Southwest Virginia) and I saw these ovens intact maybe five years ago. When we came back some time later to take photos, they were all gone.
Paraphrasing Bob Dylan’s “My Back Pages”, I was older then, but I’m younger than that now and I always carry a camera with me.
